According to Sabourin, the city aims to clear 16 per cent of the snow per day.

However, over the weekend progress may slow down as workers take a mandated break.

Sabourin said crews are only allowed to work up to 70 hours over a certain period before they must take a 24 hour break. Many of the crews, who've been working since Wednesday — when the city launched the snow-clearing — operation, have reached that maximum.

Replacement crews have been called in to make sure work does not stop entirely.
